Anybody have idea about the Circuit to convert 0-333mV Ac to 0-5 V dc.
We have CTs (Current Transformers) which are converting 0-50 Amp to 0-333mV.I need Circuit which can convert 0-333mV signal to 0-5 V dc or 4-20mA,so that I can use it with Data Logger.Thanks.

See the attached; it's a modification of a design that was in the magazine EDN.

I'm not real keen on it because the input goes below ground. However, if you used a dual rail supply (at least 6v on each rail) then it would be OK.

Interesting; it doesn't work if you use a negative rail.
The output waveform has some distortion because the input signal is partially clamped to ground via U1a's input ESD protection diodes.
